Background@#The
prevalence of
sleep disorders increases as
pregnancy progresses, which
affects the
health of
pregnant women, fetal
health, and the outcomes of
pregnancy. The aim of this study is to evaluate the quality of
sleep and
life in
pregnant women in
Korea. @*
Methods@#This study is a prospective cross-sectional,
case-control study of
pregnant women and age-matched controls. From July to September 2019, all participants completed Korean-
language versions of the
sleep questionnaires including Pittsburgh
sleep quality index (K-PSQI),
Insomnia severity index, Epworth
sleepiness scale,
Back’s
depression inventory-2(K-BDI), STOP (
Snoring, Tiredness, Observed
apneas, and
high blood Pressure), and short-form 36 (K-SF-36). @*Results@#A total of 422 participants consisted of 385
pregnant women and 137 controls. Second and
third trimester were 200 and 185, respectively. K-PSQI scores were higher in
pregnant women compared with the controls (7.87±3.49 and 8.50±3.55 vs. 5.79±2.76, p<0.001). Total score of K-SF-36 was lowest in
third trimester (62.07±17.72) and highest in the
control group(79.41±13.36). There was no statistical difference between groups in K-BDI. @*Conclusions@#This study demonstrated worsening of
sleep quality as well as
life quality during
pregnancy. More
attention to
sleep of
pregnant women is needed.
